CALLUS PROTECTOR AND ARCH SUPPORT.

Application filed January 19, 1929. Serial No. 333,549.

This invention relates to foot appliances, and more particularly to acombination callus protector and arch support.

One object et this invention is to provide a device ot the above naturewhich maybe accurately adjusted at any desired position along the lengthOf the Sole. i

el Vfurther object is to provide a device ot the above nature which willbe simple in construction, inexpensive to manufacture, easy to installand adjust, compact, ornamental in appearance, and very eiiicient anddurable in use.

l/Vth these and other objects in view there has been illustrated on thaccompanying drawings one form in which the invention may beAconveniently embodied, in practice.

Fig. l represents a bottom plan view of the invention showing thecallussprotecting and arch-supporting pad in operating' posin tion.

Fig. 2 is a similar bottom view of the same with the pad removed.

Fig. 3 is a transverse sectional view of the same taken along the line3-3 of Fig. 2.

Fig. Il is a t1agmentary longitudinal sectional view or the saine takenalong the line Ilm-1l of Fig. 1.

Fig. 5 is a perspective view oi' the buckle employed tor adjustablysecuring the pad to the insole.

Fig. G a side view et a human foot show ing the invention as it appearsin use.

Fi 7 is a top perspective view of the callus protecting` andarch-supporting pad.

Referring now to the drawings in which like reference numerals denotecorresponding parts throughout the several views, the numeral l0indicates a calins-protecting and arch-supporting pad, preferablycircular in plan view, having a spherical top and a iat base, as clearlyshown in Figs. t and 7. The pad 10 is provided with a central verticalrectangular aperture 1l for snugly receiving a buckle 12, by means ofwhich the pad l0 is adapted to be secured at any desired adjustedposition along an insole 13, preferably of leather. The upper portion ofthe pad 10 is provided with a pair of longitudinally extending1 alinedrecesses 14 and 15 for a purpose to be hereinafter described.

The insole 13 is preferably constructed from a relatively thick uppersection 16 stitched or otherwise secured to a lower section 17, thelatter being provided near its rear end with a pair oi' spaced parallelslits 18 and 19, between which is a narrow central strip 20. The centralstrip 20 is reinforced and prevented from twisting out of shape by ametal stiiiening band 21 running substantially the vlf'ull length of theinsole 13.

As most clearly shownlin Fig. `5, the buckle for attaching the pad 10 tothe strip 20 cornprises a horizontal flat base 22 from which extend apair `of vertical side wings 23 and 24 and four end prongs 25, 26, 27,and 28, said prongs being bent longitudinally at their eX- trernities tolit under the edges of the aperture 11 in the flat base of `the pad 10.`The bottom edges of the side wing`s`23 and 24 and t-he longitudinalextremities of said prongs are adapted to lie Hush with the fiat bottomsurface of said pad 10, as clearly shown in Fig. 4.

In order to permit the pad `to 1be securely held in any desired positionalongthe length oat the central strip 20, the buckle 12 is provjdedwithan angular metal tongue 29 having a normally vertical gripping section30 provided with a serrated edge 3l or engaging against said strip 20.The tongue 29 is also provided with an inclined fiat web 32 having aslot 33 in its edge for permitting the insertion of the linger of theuser for facilitating the swinging of said tongue from locked tounlocked position about the pivot pins 34 eX- tending laterally from theangular tongue 29 and located in socket-s 35 in the side wings 23 and24. A

`While there has been disclosed in this speci fication one form in whichthe invention ma be embodied, it is to be understood that this forin isshown for the purpose of illustration, only, and that the invention isnot to be limited to the speciiic 'disclosure but may be modi- `lied andembodied in various other forms without departing from its spirit. Inshort, the invention includes all the modifications and embodimentscoming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new, andfor which it is desired to secure Letters Patent, is

1. In an adjustable foot support adapted to be worn in a shoe under thefoot, an insole, a pad located under said insole, a buckle carried bysaid pad and having its base connected to said insole, said bucklehaving a pivoted tongue to detachably and adjust-ably secure said pad atany desired point under said insole.

2. In an adjustable foot support adapted to be worn in ashoe under thefoot, an insole comprising upper and lower layers, a pad located undersaid insole, a buckle carried by Said pad and having its base connectedto the lower` layer of said insole, said buckle having apivotedtongue todetachably and adjustablyv secure said vpad at any desired point undersaid-insole. l
